FIN — Fridge.com Identification Number

What is a FIN?

FIN stands for Fridge.com Identification Number. It is the permanent canonical anchor that Fridge.com assigns to every refrigerator, freezer, ice maker, beverage center, wine cooler, kegerator, and similar refrigeration appliance in our database. The format is FIN- followed by a zero-padded seven-digit number, for example FIN-0042893. Every FIN is unique and never changes, even when manufacturer model numbers are re-normalized or product pages are restructured. The FIN is the spine of the Fridge.com Product Intelligence Layer: it links the same physical model across Amazon, Home Depot, Best Buy, Lowe's, Walmart, AJ Madison, and the manufacturer's own site, so price history, customer reviews, recall notices, and specification documents all aggregate cleanly under a single identifier.

What is a FIN?

The Fridge.com Identification Number system, explained.

FIN stands for Fridge.com Identification Number. It is the permanent canonical anchor we assign to every refrigerator, freezer, ice maker, beverage center, wine cooler, kegerator, and similar refrigeration appliance on Fridge.com.

The format is FIN-0042893 — three letters, a hyphen, and a seven-digit zero-padded number. Every FIN is unique to one physical model. Once a FIN is assigned, it never changes, even if we re-normalize the manufacturer's model number or restructure a product page. The URL stays permanent because the FIN is built into it.

Why FINs matter

Every retailer assigns its own internal SKU to the same physical refrigerator. Amazon calls a Samsung 4-Door Flex an ASIN like B0CM5R97SV. Best Buy gives it a SKU like 6520283. Home Depot uses a different number entirely. Without a canonical anchor, you can't reliably aggregate review counts, price history, or recall notices for the same physical product across stores.

The FIN is that anchor. It lets Fridge.com link the same physical model across every retailer that sells it, so when you look at a refrigerator's page, you see the full picture: years of price history, the lowest current price across all retailers, real customer reviews from Amazon plus Home Depot plus Best Buy plus Lowe's plus Walmart plus AJ Madison plus the manufacturer's own site, any active CPSC recall notices, and the manufacturer's spec sheets and owners manuals — all under one identifier.

Where you'll see FINs

FIN versus model number

The FIN is ours. The manufacturer's model number (e.g., RF23DB9900QDAA) is theirs. Both appear on every product page. The model number tells you exactly what you're buying. The FIN tells our systems how to keep that product's data stitched together across the whole web — for as long as the product exists, and for historical reference long after it's discontinued.
